Title	Composition of Narbada and Tapti estuarine particles and adjacent Arabian Sea sediments

Creator	Borole, D V Sarin, M M Somayajulu, B L K

Description	51-62 Composition of suspended matter collected from Narbada and Tapti estuarine waters and of the sediments from the near-coastal and open shelf and slope regions of the Arabian Sea is reported. Metal/Al ratios, which essentially indicate the clay composition, remain unchanged (within ± 20%) from one end of the estuary to the other and in the near-coastal sediments indicating that the adsorption-desorption reactions are within the scatter (within ± 20%) itself. In the anoxic open shelf and slope regions, Ni, Zn and U are enriched whereas Mn is depleted. Aughigenic deposition of Ni and Zn as sulphides, U in the +4 valence state and diffusion of reduced Mn (Mn⁺²) are the most probable causes. Suspended fluxes of Al, Fe, Mn, Cu, Ni, Zn and U and their deposition rates in the Coastal Arabian Sea Regions during the past 1100 yr are estimated.
